the general form of the linear equation is
where m is the slope and b an initial point
we have m just need find b, we can replace the slope and the point and solve b
so the linear equation is
Sugar (sucrose - C12H22O11)
Table salt (sodium chloride - NaCl)
Water (H2O)
Carbon dioxide (CO2)
Sodium bicarbonate (baking soda - NaHCO3)
"Circumscribed rectangles" means that any Riemann Sum (left or right) must overestimate the area under the curve. So, a Right-Riemann sum would underestimate the area under the curve, and that's where you made your mistake. You will use the Left-Riemann Sum to approximate the area under the curve r(t) = tan(cos(xt) + 0.5) + 2
Or, you could use u-substitution to get the <em>exact</em> area under the curve from [0, 12] - but I would do as the problem says. If you want me to that, DM me.
I think x gonna be 7 cause if u see 8 multiply by 2 will be 16 so if u use the trick with 14 then u answer will come 7.(7.2= 14).
Cancel out units you don't want in your final answer...
880w(32sec/800w)=35.2 seconds
